Question

use circle e to answer the following questions:

m\\(\widehat{ab}\\)=

m\\(\angle aeb\\)=

m\\(\angle acb\\)=

m\\(\widehat{adb}\\)=

Explanation:

Step1: Recall circle - arc relationship

The measure of an arc is twice the inscribed - angle subtended by it. The central angle has the same measure as its intercepted arc.

Step2: Find \(m\widehat{ADB}\)

The sum of arcs in a circle is \(360^{\circ}\). Given \(m\widehat{AB}=40^{\circ}\), then \(m\widehat{ADB}=360 - 40=320^{\circ}\).

Answer:

320
